How to ignore .aj files?https://www.eclipse.org/forums/index.php/mv/msg/188102/596711/#msg_596711
as an AspectJ project right now, but I still get a couple of errors in
aspects.

Since I currently don't want to deal with these but need to fix some bug
in the barebone (i.e. the underlying original) project (but on the other
hand don't want to remove those .aj files, either) I would like to
simply ignore or "remove from seeing" these .aj files in the .java
perspective. Can I do that and tell AJDT to NOT treat that project as an
AspectJ project (but as a pure .java project only) for the time being?
